GAS BARRIER LAMINATE AND PACKAGE

The purpose of the present invention is to provide a gas barrier laminate which can be produced by a simple process and which can obtain stable gas barrier properties even at high humidity. The present inventors can obtain a gas barrier laminate that can be produced by a simple process and that can obtain stable gas barrier properties even at high humidity by using a gas barrier laminate in which a metal layer (A) formed by a gas phase thin film formation method and a layer (B) formed from a compound having a carboxyl group in the structure are laminated. Therefore, the above problem is solved. 本发明的目的是提供一种气体阻隔性层叠体，其能够以简便的工序来制造，且即使在高湿度下也可获得稳定的气体阻隔性。本发明人等利用层叠有通过气相薄膜形成法而形成的金属层(A)、及利用在结构中具有羧基的化合物而形成的(B)层的气体阻隔性层叠体可获得能够以简便的工序来制造、且即使在高湿度下也可获得稳定的气体阻隔性的气体阻隔性层叠体，从而解决了上述课题。
